The present invention has particular re lation to hat pressing machinessuch as disclosed in Letters Patent of the United States. granted to meunder date of J anuary 26, 1915, numbered 1,126,492, to which patentreference is here made.

Description.--As seen in the drawings, the herein disclosed machine hasa cup.-

' shaped crown mold 15, a hydraulic head 16 for filling the same and forexerting expansive pressure therein, a male brimdie '17 and a femalebrim die 18. The mold and die 17 are both-removablydisposed, on astationary steam heated. table 19. The die 18 is permanently attached toa movable steam heated table 20.3 The head 16 is preferably constructedof rubber or other extensible material and: is suspended from a closureplate 21. The closure plate 21 is operatively 1 connected "with a feedscrew- 22, which is operatively engaged by a nut 23 to be ele- Yated anddepressed. A hand. wheel 24 is connected with the'nut: 23 to facilitatethe manipulation of the said nut. The hand wheel'2 l is held firmly inposition by a retaining nut 25. The screw 22 is tubular forming aconduit for the passage of water from a supply pipe 26 to the interiorof the head 16. It will be understood that the supply of water furnishedby the pipe 16 is manually controlled and is under suitable pressure. Itwill alsobe understood that the tables 19 and are hollowed to receivesteam supplied for heating thesaid tablesto the necessary or desireddegree. The table 19 is cupped to form aichamber 27 wherein rests themold 15'to be guided thereby. The mold 15 is supported by a heated tip'28, which like the tables 19 and 20 is hollowed for heating bysteamadmitted thereto. The table 19 has a lower opensided extension 29, inwhich is houseda tubular adjusting nut 30. The nut 30 operativelyengages a screw threaded plunger .31 to elevate and lower the same.v Theplunger 31 has a head 32 perforated to receive the'pins 33 for pivotallysupporting the tip 28 and mold 15 resting thereon. 1

The nut 30 is freely accessible, entrance being gained thereto from theopen sides of the housing 29. The nut is furnished with a series ofspanner holes 34, by which the nut may be turned to adjust the tip 28and mold 15 to the desired operating position. The not 30 is closed atthe lower end'by a screw cap 35, which is centrally perforated to passtheshank of a connecting screw 36, the head 37 whereof rests within thenut 30, the inner wall whereof is rabbeted adjacent'the lower edge toform an annular shoulder or rest for the head 37.

' The screw 36 and the head 37 thereof are freely movab e in the cap andnut 30. The screw is fixedly mounted in acollar 38.

The'collar .38 fits theeccentric '39 01,1 the,

shaft to be raised and lowered thereby, for moving the crown mold 15after the setting pressure has been applied to the dies 17 and 18 andbetween the head 16 and the wall of the mold 15, as hereinafterexplained. For manipulating the shaft 40, a lever 41 is fixed thereto,said lever being disposed in a horizontal extension when the parts ofthe mold are separated, as seen. best in'Fig. lof .the drawings. thelift of the mold 15 and tip-28 is dependent on the throw of theeccentric '39.

The head 16 and table 20 by which the same is supported, is lowered andraised by a distributer bar 42. The bar 42 as seen best in Fig. 8 of thedrawings, is furnished at the opposite ends with brackets 43, forsupporting at the upper ends thereof, collars 44. The collars 44 receivethe connecting rods 45, which at the upper end have threaded extensions46 held in adjusted relation by the nuts 47 that bear on both sides ofbracket extensions- 48 set out from the table 20. i I

The setting pressure-for thedies l7 and 18 is obtained by rocking theshaft '49. The

shaft 49 is mounted in bearings 50 formed in the extensions 43 of thebar 42. F ixedly mounted on theshaft 49 are heavy eccentrics 51disposed, as seen best.- in Fig. 1' of the drawings, in juxtaposedrelation to the extensions 43. The eccentrics 51 rotate within thecollars 52 formed at the ends of the arms 53, which are connected as arigid structure by a brace 54. 'The upper ends of the arms 53 areyoked'to form divided hinge knuckles 55, the ends whereof are perforatedto receive the pins 56 when the same are passed through correspondingperforations formed in the arms 57. The arms 57 are rigidly connected bya brace 58.. The arms 53 and 57-are so connected bv the pins 56 that inservice, the center of the said pins and the center of the collars 52and the bearings 59 at the upper ends of of the arms 57 are slightly outof line, the

said pins thereof passing the; plane. with which the centers of the saidcollars and bearings are coincident.v To regulate the distance to whichthe pins pass the said plane, there are provided the set screws 60. Thescrews 60 are each mounted in threaded perforations tapped in the outerend of 01f sets 61. The offsets 61 have a flat surface to register witha corresponding surface on offsets 62 formed on the arm 63. T he endsofthe screws 60 bear against. the surface of the offsets 62 and bypreventing the too close abutment of the offsets 61 and 62,

regulate the swing ofithe arms 53 and 57" to and past the verticalplane.

The arms 57.are united with webs 64,?

The extent of integrally formed with the frame table 66: From theforegoing, it will be seen that when the arms 53 and 57 have beenstraightened, a. thrustis exerted therethrough by.

the eccentrics 51, when the shaft 59 is rocked. Through the shaft 49,pressure isexerted to the distributer bar 42' to lower- .the same andthereby through the medium of the rods 45, forces the die 18 on the die.

a shaft 69. Thebar 42 and parts connected therewith are'normallyheld intheposition shown in Figs. 2 and 3 of the drawings, by-v thecounterbalancing weight 70. The :wedge 7 0 is slid-ably mounted 7 on ithe rod 71',

which is held bv a set screw 72 in a socket 1 1 member 73. The' socket'member 73 is formed at. the rears, end of a rocking.

arm 74. The arm 74 andmember 73 formed therewith, are both supported bya pivot shaft 75.

connected with thebar 42by links 7 6. The

links 76 are united by pins 77 with. lugs 78 on the bottom'of the bar42, as seen best, in Figs. 3 and 8 of the drawings. To

The arm .74 is flexiblyassist in supporting the weight of thebar 42 andmemberssupported thereby, the. coil springs-79 areconnected to a shaft380; Asseen in Fig. "1,"a batterv of springs is einplovedi These/maybeincreased or reduced in number according as the work required thereofdemands. The weight 170 is shifted on the rod 71 to modify the *actionof the arm 74 by ass sting the springs 79. The weight 70 is adjusted ontherod' 71 and held in fixed relation'thereon by'a set serew.81.:

The lever 67 is-operativelv connected with the arm 74by'bowed links 82,said links being connected'with a lug=83, by.

means of a pin 84; The connection between the lever 67 and the links82is made by r a pin 85, as seen best in-Figs. 1 and 3 iOf the drawings.
